On an earlier contract in China, Vlada received just £6.30 a day for her catwalk appearances once her air fares, hotels, food and insurance had been taken from her earnings, reported the Russian media.

The girl was “scared” to seek hospital treatment because she did not have medical insurance on her latest trip to China, say the media citing her mother.

The Chinese modelling agency involved in her latest trip has denied overworking her – but new facts have emerged that raise concern over the working conditions of a girl who was not accompanied by her mother.

Among these is the length of her employment hours, which could be more than eight hours a day, and how she could be in China without medical insurance.
